UNITED STATE-s PATENT OFFICE.

ALEXANDER STUART, OF SPRINGFIELD, OHIO, ASSIGNOR TO THE SPRING- FIELD ENGINE AND THRESHER COMPANY, OF SAME PLACE.

HORSE-POWER.

SPECIFICATION forming part of Letters Patent No. 277,375, dated May 8, i883. v Application filed March 26,1883. (No model.)

To all whom it may concern A Be it known that I, ALEXANDER STUART, of Springfield, county of Clarke, Stateof Ohio, have invented anew and useful Improvement in Horse-Powers, of which the following is a specication.

This invention is designed as an improvement on that type of horse-powers known as the Woodbury Power, andv it consists in the construction and arrangement of parts as hereinafter fully specified.

In the accompanying drawings, Figure 1 is a plan view of a horse-power embodying my improvements, and Fig. 2 is a sectional elevation ofthe same. In these drawings I have omitted such parts of the machine as are not necessary to a perf'ect understanding of my improvements, and letters of like character indicate corresponding parts in each of the iigures.

With machines of this character as formerly constructed the gear-shaft a was very liable to spring out of alignment, thereby partially destroying the usefulness of the machine. To obviate this difficulty I employ a bearing, b, that is located close to the transmitting gearwheel c. d, that is secured to the metallic frame e at f, and to the cross-tie h at i, by which construction and arrangement-I have three bearings, j k b, for the support of shaft a. Two of these bearings are close to and on each side of the wheel c, which enables me to hold the piuions lm and wheel c to their work and in proper alignment. The bearing b is' not cast in a piece with the arch d, but is secured to it by means of slides b b', that tit into ways n n', formed on the arch d, and screw-bolts p, that pass through the aforesaid bearing and arch.

This bearing is mounted on an arch,

bearing b may be renewed at any time without disturbing the arch d, which forms a rigid support for said bearing. The arch d is secured to the metallic frame c at one end and to the cross-tie h at the other by screw-bolts. 45

It will beeasily understood that with such a construction and arrangement of parts the shaft a may be of less diameter than it could be if the bearing b were not employed, and at the same time it would, when so reduced and 50 supported, be less liable to spring and throw the gearing out of mesh. i

Havingthus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. Ina horse-power mechanism having the 55 frame e and crosstie h', the combination of the shaft a, supported by end bearings,j k, and carrying the piuions l m and gear-wheel c,

with the arch d, in line with the said shaft, 6o

to the cross-tie h, and the bearing b, detach- ;o

ably secured ,to the arch by slides b' land screws p', substantially as described.

In testimony whereof I have hereunto set my hand thisv23d day of March, 1883.
